Review of the leaf found the seams a stranger on the other end of a D connection could pull at, and a few that a slow one would. - A code-93 envelope is unwrapped once, as Nicotine+ does; a frame made of nothing but envelopes used to recurse once per byte. - A branch level is validated before it is used: negative levels leave the candidate unadoptable and the largest one no longer overflows. - The link reads through the crate's MessageReader, so a frame split across a read timeout is no longer torn or mistaken for a closed link. - Every event a link raises carries its link number, so a stale thread cannot adopt, close or move a newer link to the same user. - Later branch facts from the parent move our own place and are told to the server; a fresh login resets the leaf, whose stance is now the one place the four announcement messages come from. - Candidates from a later batch join the ones in flight instead of cancelling them, capped at ten; searches from the parent are budgeted at fifty a second; a reply queued for a searcher the server cannot place expires after a minute. - Truncated frames and half-read PossibleParents entries are dropped instead of yielding an empty root, a level of zero or a phantom candidate. The e2e now has a searcher of its own, so the answer must go to whoever asked and not to the parent that relayed it.
soulseek-rs-lib
A Rust library for implementing the Soulseek peer-to-peer protocol.
Website: https://re-invention.nl/soulseek-rs/
About
This library provides the core functionality for interacting with the Soulseek network. It can be used to build custom Soulseek clients.
Usage
Add this to your Cargo.toml:
[dependencies]
soulseek-rs-lib = "8"
Example
Simple Usage
use soulseek_rs::Client;
use std::time::Duration;
fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create and connect to Soulseek server
let mut client = Client::new("username", "password");
client.connect()?;
client.login()?;
// Search for files
let results = client.search("Alex Kassian lifestream", Duration::from_secs(10))?;
// Download first available file
if let Some(result) = results.iter().find(|r| !r.files.is_empty()) {
let file = &result.files[0];
let (_download, status) = client.download(
file.name.clone(),
file.username.clone(),
file.size,
"~/Downloads".to_string(),
)?;
// `download` returns as soon as the request is queued: the transfer is
// finished when the channel says so, not when this call returns.
for update in status {
println!("{}: {update:?}", file.name);
}
}
Ok(())
}
Advanced Configuration
use soulseek_rs::{Client, ClientSettings, PeerAddress};
fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create client with custom settings
let settings = ClientSettings {
server_address: PeerAddress::new("server.slsknet.org".to_string(), 2416),
enable_listen: true,
listen_port: 3000,
..ClientSettings::new("username", "password")
};
let mut client = Client::with_settings(settings);
client.connect()?;
client.login()?;
Ok(())
}
Asking about a peer
The server-backed lookups are request/poll pairs: you ask, then read the
answer once it lands. request_user_info clears any previous answer first, so
the loop below observes this request rather than the last one.
use soulseek_rs::Client;
use std::thread::sleep;
use std::time::{Duration, Instant};
fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut client = Client::new("username", "password");
client.connect()?;
client.login()?;
client.request_user_info("someuser")?;
let deadline = Instant::now() + Duration::from_secs(10);
while Instant::now() < deadline {
if let Some(info) = client.user_info("someuser") {
// Presence and stats are separate replies, so each is an Option:
// a reply that never arrived is None, not "offline" or "shares nothing".
println!("{:?} {:?}", info.presence, info.stats);
break;
}
sleep(Duration::from_millis(100));
}
// Room membership is kept current from join and leave events.
println!("{:?}", client.room_members("lobby"));
Ok(())
}
ClientOperation is #[non_exhaustive]: every protocol message the client
learns to handle adds a variant, so match it with a wildcard arm. SharedFile
is too, so build it with the .. syntax rather than listing every field.
